The present invention relates to a thresher capable of performing a leak sorting with an installed grain sieve.

[Conventional technology]

In this type of thresher, as shown in Japanese Patent Application No. 1-5688 filed by the applicant of the present invention, the grain pan can be slidably moved in a predetermined range in the front-rear direction with the front grain pan fixed in position. A technique has been proposed in which a rear Glen Pan is connected to the front and the rear, and the rear Glen Pan is slid to open and close according to the amount of threshed material.

[Problems to be Solved by the Invention]

However, the above-mentioned conventional technology only mentions the function of opening and closing the rear Glen pan, and it has not been clarified how to open and close the rear Glen pan according to the amount of the processed material.

An object of the present invention is to provide a thresher capable of effectively utilizing a slide opening / closing type Glen pan.

[Means for solving the problem]

In order to achieve the above object, the present invention, in the threshing machine described at the beginning, a front Glen pan of which the position of the Glen pan is fixed and a rear Glen pan slidable within a predetermined range in the front-rear direction are connected in front and back. In addition to the above configuration, means for detecting the amount of fluctuation per unit time of the grain culm sent to the handling room provided with the handling barrel is provided, and the rear part is provided with the detection means detecting an increase in the amount of grain culm. Automatic control that automatically moves the Glen pan forward and automatically moves the rear Glen pan backward when it detects a decrease in grain culm volume. The mode and the rear grain pan is moved to the frontmost position to be fully opened regardless of the variation detection information of the grain culm by the detecting means, and the rear grain pan is intermittently opened. Wherein configuration that person are to emerge configured to be able to alternatively select and a cleaning mode that reciprocates moves towards the closed state moves to.

[Work]

When the amount of processed products sent to Glen Pan is large,
While increasing the filtration area of the Glen sieve following this Glen pan to have sufficient sorting capacity, when the amount of the treated material is small, the filtration area of the Glen sieve is reduced, and it exists in the upper layer of the treated material layer by the specific gravity difference sorting by the Glen pan. Good sorting can be done if dust such as cut straw is not filtered.

Since the detecting means can detect the change in the amount of grain culm sent to the handling room, that is, the change in the amount of processed material per unit time, the Glen pan is opened / closed according to the detection result of the detecting means, and the grain sieve By setting the automatic control mode in which the filtration area is automatically increased or decreased, the above-described good selection can be automatically performed.

In addition to the automatic control mode, it is possible to select a cleaning mode in which the rear Glen pan is basically fully opened independently of the detection means, so that, for example, during wet threshing,
It becomes a state suitable for sorting processed items that are difficult to sort, and by intermittently closing the rear Glen pan, peeling off wet straw dust and dust adhering to the Glen sieve and cleaning the Glen sieve. It also allows the action to occur.

〔The invention's effect〕

Therefore, since the grain sieve area can be increased or decreased according to the actual increase or decrease of the processed material, the sorting performance is further improved, and the control is automatically performed, so that the Glen pan is always opened and closed compared to the case where it is operated artificially. The labor and time to pay attention to the increase and decrease of grain culm can be saved, and wet threshing can be dealt with.Besides, the corresponding state can always be maintained without causing clogging due to the cleaning action of the Glensieve, so workability is improved. , The operability was improved and the sorting performance could be reasonably improved.
